power window 3 prong safety relay
The power windows operate slowly, but connecting 12 volts directly to the motors allows them to function properly. A previous discussion mentioned using a common 5-pin ice cube relay, but there was no confirmation of its effectiveness. The power window...
mains ac relay module
This mains AC relay module utilizes 5V relays that can be powered directly from an Arduino and can switch 230V. A basic energy monitoring and control system has been constructed using an Arduino 2009, off-the-shelf wireless remote control sockets, and...
Two Simple Relay Based Motorcycle Alarms circuit
Relays can be utilized to protect motorcycles and have various other applications. When using relays with 6-volt coils, they provide security for "Classic Bikes." The alarms are compact, with completed boards occupying approximately half a cubic inch (8 cc). The...
Multivibrator
In a previous chapter, the use of a transistor as an electronic switch was discussed. This chapter will explore how one transistor can switch another. The diagram illustrates a pair of cross-coupled transistors. The input push buttons of the circuit...
The NOT gate
The single-transistor inverter circuit discussed earlier is too simplistic for practical use as a gate. Real inverter circuits utilize multiple transistors to enhance voltage gain, ensuring that the final output transistor is either in full cutoff or full saturation, while...
DC relay circuits to delay the release of a second
The circuit depicted in Figure 6-24 includes a relay coil with both ends connected in parallel to either a resistor Rf or an auxiliary diode VD. This configuration is equivalent to providing power after a short circuit, which increases the...
12 V High current regulator
This voltage regulator circuit can deliver up to 3A at a 12V output voltage. The circuit can be used when a current exceeding 3A is required for regulation. Integrated circuit (IC) regulators with such high current ratings are relatively difficult...
Motor vehicle steering flasher 12
The motor vehicle steering flasher described in the example utilizes high-power transistors as electronic switches, and the circuit is simple and easy to construct. The motor vehicle steering flasher consists of the flash circuit with resistors R1-R3, a capacitor C,...
Simple Short Finder Circuit
Transistors Q1 and Q2, along with resistors R1 through R7, form the input balancing stage that measures the resistance between points X and Y. This stage operates as a bridge circuit, incorporating resistors R1, R2, R6, R7, and the resistance...
